Cantaburros is the name of the vineyard location and is located in the very heart of the Ribera del Duero region on the central plateau of Spain, in Castilla Leon region. It belongs to San Pablo company, two families owners since 1989. Poor, dry, calcareous and covered with stones, the vineyard is located at an altitude of approx. 800 m, where winters are freezing cold and summers extremely hot, where the difference between day and night temperatures can vary up to 25º. Rough and rustic as the location, Cantaburros (singing donkeys) also seemed a perfect name for a wine produced under such circumstances. The surface area is now 38 hectares. Bearing in mind how essential the environment is to the vine, it is their wish and obligation to respect and interfere as little as possible and the wines are organic following the standards of ecological agriculture stipulated by the EU and CAECyL.
